Servicing the Mower Deck
Gear Box Lubricant
The gear box is designed to operate with SAE 80-90 gear
lube. Although the gear box is shipped with lubricant from
the factory, check the level before operating the cutting unit
for the first time and every 150 operating hours thereafter.
Change the lubricant in the gear box every 400 operating
hours.

Servicing the Bushings in the
Castor Arms
The castor arms have bushings pressed into the top and
bottom of the tube and after many hours of operation, the
bushings will wear. To check the bushings, move the castor
fork back and forth and from side to side. If the castor
spindle is loose inside the bushings, the bushings are worn
and must be replaced.
1. Raise the cutting unit so that the wheels are off of
the floor. Block the cutting unit so that it cannot
accidentally fall.
2. Remove the tensioning cap, spacer(s), and thrust
washer from the top of the castor spindle.
3. Pull the castor spindle out of the mounting tube.
Allow the thrust washer and spacer(s) to remain on
the bottom of the spindle.
4. Insert a pin punch into the top or bottom of the
mounting tube and drive the bushing out of the tube
(Figure 19). Also drive the other bushing out of the
tube. Clean the inside of the tubes to remove dirt.

5. Apply grease to the inside and outside of the new
bushings. Using a hammer and flat plate, drive the
bushings into the mounting tube.
